Embodiment Construction

[0063] The implementation flow chart of the present invention is as figure 1 As shown, the specific implementation is as follows:

[0064] In order to solve the situation of noise correlation, the present invention proposes a volumetric information filter (SCIF-CN) design method under noise correlation conditions, so as to achieve the purpose of tracking the target. In order to describe the content of the present invention conveniently, at first the present invention establishes a model for the single-sensor target system, and it comprises 2 equations, state equation and observation equation, respectively as follows:

Abstract

The invention relates to a capacity information filtering-based pure direction tracking method of a noise-related system, which belongs to the field of target tracking. The conventional capacity kalman non-linear system target tracking method is implemented on hypothetic premise that process noise is not related to measurement noise, so that the use range of the method is greatly limited. According to the method, on premise that expanded kalman information filtering related to the noise is deducted, capacity kalman information filtering is embedded into two processes of time updating and measurement updating. The problem of noise relevance is solved, and therefore the practicability of the method provided by the invention is greatly improved.

Description

technical field [0001] The invention belongs to the field of target tracking, and mainly relates to a direction-only target tracking method based on volume information filtering in a noise correlation system. Background technique [0002] Sensor target tracking is a multidisciplinary technology. In recent years, with the development of sensor technology, computer technology, communication technology and information processing technology, especially the urgent needs of the military, the research content of multi-sensor target tracking technology has become increasingly in-depth and extensive. In the military, it is mainly used in command, control, communication and intelligence systems, and it also has important application value in the fields of robotics and civil aviation control. At present, there are many better algorithms for target tracking, such as Kalman filter algorithm (KF), unscented Kalman filter algorithm (UKF), volumetric Kalman filter algorithm (CKF), etc. How...
